So far the giant Pacific octopus has had a mixed tournament: he predicted an England win against France, but psychic or not, he seems to be an optimistic England supporter.

His handler Hannah Deeble said: “He may lack the precise predictive powers of Paul the German octopus but he’s clearly an England fan at heart and, perhaps like the team themselves, he’s taking his time to warm up.

“Sherloctopus confidently went for an English win in their opening match but he’s been a little more cautious this time around and has predicted the Swedish game will end in a draw."

She added: “We don’t claim he’s infallible but he’s certainly entertaining and it would be boring if he was always right!”

Giant Pacific octopus are the world’s largest species of octopus and are found from Japan to Southern California. The biggest recorded specimen had an arm span of 10m (33ft) and weighed 270kg (600lbs).

As well as being the largest, the giant Pacific is also among the cleverest members of the cephalopod family. Individuals living in aquariums have been filmed sneaking out at night to raid nearby fish-filled displays.

Despite their intelligence giant Pacific octopus are relatively short lived - going from the size of a rice grain at birth to being fully grown within the space of two years.
